{{lua|Module:URL}}


This template can be used to create a formatted external link. It formats the appearance of '''''displayed''''' URLs, while making them ''machine-readable'' as part of emitted [[microformat]] meta-data, inside templates such as infoboxes.

If you wish to display text instead of the URL (e.g. "[http://example.com website]" instead of {{URL|example.com}}), please '''do not use this template'''. Instead, consider using normal [[Help:Link#External_links|wiki markup]], [[Template:Plain link]], or [[Template:Official website]]. Displaying text instead of the url will render the microformat data invalid.

For web-based references, please see [[Wikipedia:Citation templates]]''

== Usage ==
* <code><nowiki>{{URL|</nowiki>''example.com''<nowiki>}}</nowiki></code>
** The first parameter is parsed to see if it takes the form of a complete URL. If it doesn't start with a URI scheme (such as "http:", "https:", or "ftp:"), an "http://" prefix will be prepended to the specified generated target URL of the link.
** Parameter 2 (<code><nowiki>{{URL|</nowiki>''url name''<nowiki>|</nowiki>''optional display text''<nowiki>}}</nowiki></code>) is '''deprecated'''. See note above for more information and alternative templates.

'''Warning:''' The parameter 1 must be numbered explicitly (<code><nowiki>{{URL|</nowiki>1=''example.com''<nowiki>}}</nowiki></code>) if the URL contains an equal sign, as is common in a query string. This applies when the value of the URL is unknown, for example when this template is used in another template specifying the effective URL as a variable value. The ''deprecated'' second parameter for the displayed text, if present in legacy uses, '''must''' also be explicitly numbered if the first parameter is explicitly numbered (<code><nowiki>{{URL|</nowiki>1=''url name''<nowiki>|</nowiki>2=''optional display text''<nowiki>}}</nowiki></code>); otherwise it will override the value of the first parameter.

== Microformat ==
The template wraps the ''displayed'' URL with a <code>class="url"</code> so that it is included in any parent [[microformat]] which takes a URL parameter - see [[WP:UF|our microformats project]].
